“…In fact, the monomer reactivity ratios were reported to be r 1 = 1.17 and r 2 = 0.58 for the copolymerization of styrene (M 1 ) and AAm (M 2 ) in the literature. 43 The SS monomer is one of typical conjugating monomers, for example, r 1 = 7.19 and r 2 = 0.084 for the copolymerization of SS (M 1 ) and N -vinylpyrrolidone (M 2 ). 44 These literature values also supported the predominant propagation of SS and the lower reactivity of AAm during the copolymerization.…”

“…Under the conditions of the coexistence of a highly conjugated SS monomer and a relatively less-conjugated AAm monomer, the propagation rate of SS was much greater prior to that of AAm. In fact, the monomer reactivity ratios were reported to be r 1 = 1.17 and r 2 = 0.58 for the copolymerization of styrene (M 1 ) and AAm (M 2 ) in the literature . The SS monomer is one of typical conjugating monomers, for example, r 1 = 7.19 and r 2 = 0.084 for the copolymerization of SS (M 1 ) and N -vinylpyrrolidone (M 2 ) .…”

In this study, we propose a convenient method for the synthesis of double-network gels by the one-shot radical polymerization for their application to rapid optical tissue clearing. Double-network gels were produced during the radical polymerization of acrylamide (AAm) and sodium styrenesulfonate (SS) in the presence of N,N′-methylenebisacrylamide and sodium divinylbenzenesulfonate as the cross-linkers by simultaneous addition, that is, one-shot polymerization accompanying the delay of polymerization for a second network monomer. We analyzed the polymerization process based on the consumption rates of each monomer during the reactions in the absence of the cross-linkers in order to estimate the repeating unit structure of the resulting polymers. We then fabricated the AAm/SS gels by the polymerization of AAm and SS in the presence of the cross-linkers. We analyzed the swelling, viscoelastic, and mechanical properties of the produced gels to investigate their network structure. Finally, we demonstrated the validity of the double-network gels for the application to rapid optical tissue clearing.

“…The pK a value varies with experimental conditions such as temperature, ion strength, and salt used for controlling ion strength. 17,18 For reference, ionization constant for poly(acrylic acid) (PAA) was measured in the same conditions, and pK a ϭ 5.22 and n ϭ 2.03 were obtained. It is understandable that PMGly is easier to dissociate than PAA.…”
